causeyoudaoicibaDictYouDict[cause 词源字典]
cause: [13] Cause comes via Old French cause from Latin causa, which as well as ‘reason’ meant ‘law-suit’; this was carried over into English legal language (it survives in terms such as cause-list ‘list of cases to be tried’) and its use in expressions like ‘plead someone’s cause’ led in the late 16th century to a more general application ‘goal or principle pursued or supported’. French chose ‘thing’ also comes from Latin causa, in the weakened sense ‘matter, subject’.
